Review: This is a replacement for the first unit that died - For the money this is a very good water testing system. I use it to monitor a remote pool and it works well for that purpose. It sits in the skimmer & tests the water daily. You can set the time of day, but no option to skip test days. I think I used two cartridges a season in NorthEast. It tests free chlorine, pH, water temperature & water flow at the skimmer. It has helped immensely, but disappointed it stopped responding after two seasons. Worth the money & relatively inexpensive compared to the few competitors. Cartridge 5-pack is $50. It is accurate & does require wifi to work. They provide water testing for detailed analysis, but my two tests did not get uploaded this season. You can manually upload detailed pool test data if you have a local tester. This house is remote so testing water locally is challenging. The app interface is easy to use & they calculate estimates for what product to add based on pool size. You can have multiple units & share the access to family members. Worth the money, no green pool for two years. Buy long lasting Lithium C batteries, the extended use is well worth the extra cost. Review: DO NOT PURCHASE!!!!! Useless after 30 days… - DO NOT purchase!!!! First which really isn’t advertised, you spend $350 for basically a drain cover and holder for the testing/sending cartridges which must be replaced every 30 days. When the cartridge reaches 30 days it stops testing the water and updating the app. Here is the kicker you can only buy the cartridges directly from Waterguru for around $80, but they are supposedly having supplier issues getting the replacement cartridges and you cannot get them. So after 30 days and spending $350 the Smart Pool Monitor is useless and dead in the water…. This company is scamming people selling products that will stop working in 30 days. ## Features - Exclusive Compatibility – The WaterGuru SENSE S2 works exclusively with two cassette options: the C5 Cassette (included with purchase) and the C2 Cassette. The C5 Cassette lasts 1 month with daily measurements, while the C2 Cassette lasts 2 months with daily measurements. - Fits Most Skimmers – Adapters Available if Needed! WaterGuru SENSE S2 fits round skimmers between 8.25” and 9.4” without an adapter. For 10” square skimmers, use the WaterGuru Square Adapter.

No test strips required. Step-by-step guides, FAQs, and troubleshooting are available in the WaterGuru App. - Wi-Fi Setup Guidance – Connects to your home Wi-Fi for automatic daily readings. For best performance, ensure the device is within 30 ft of your router or mesh node.

The app shows your levels and provides custom advice based on your pool type, size, and chemicals to keep water balanced. **Q: What’s in the Box?** A: Includes the WaterGuru Sense S2, a C5 Cassette, 4 C batteries, a float ring for spas or above-ground pools, and a Quick Start Guide to help you install and get set up in seconds—everything you need to start smart pool monitoring right away. **Q: Do I need Wi-Fi access near my pool for the WaterGuru SENSE to work?** A: Yes. You will need Wi-Fi access at the pool area where the WaterGuru SENSE will be installed. **Q: WaterGuru Pool Skimmer Monitor vs. Floating Pool Monitor – What’s the Difference?** A: Floating monitors can drift, get damaged, or pose safety risks in active pools. WaterGuru Sense sits safely in your skimmer, out of the way, and delivers more stable, accurate readings by staying in constant water flow—no interference, no hassle. **Q: Pool Test Strips vs. WaterGuru Chemical Monitoring?** A: Test strips are time-consuming and often inaccurate. WaterGuru Sense sits in your skimmer and uses smart optical sensors to test key chemical levels. View results in the app with personalized advice—no guesswork, color matching, or manual testing. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This is a replacement for the first unit that died *by M***E on 8 November 2024* For the money this is a very good water testing system.

The installation was very straightforward. Install the batteries, plug the cartridge into the sensor, then drop the sensor into the skimmer and you're done. And don't forget to install the app on your phone and connect to the sensor via Bluetooth and WiFi. After a short period of time, I got feedback on my phone about the current conditions of the pool: pH level, free chlorine (FC), total alkalinity (TA), cyanuric acid (CYA) level, and calcium hardness (CH). If you use salt to soften the pool (or I suppose if you have a saltwater pool) there's data for that as well. My pool had been serviced the day before so I expected the readings to be high. No surprise that the pH level was high, the TA was high, and the CH level was high. Over the next couple of days, I watched the levels drop closer to the normal range--and I intend to share the results with my pool maintenance company so they can manage my pool more effectively. My 'pool guy' is already excited to see the results to help him save time, money, and chemicals during his regular maintenance schedule. If I want to do it myself, I now have enough detailed information about what chemicals (acid, chlorine, etc.) need to be added and in what quantities to make it a manageable task. The Water Guru Sense S2 is a game-changer for pool maintenance. It eliminates the guesswork, can save you money, and at the very least, provides actionable insight into the state of your pool. If you're using the pool on a regular basis, or have kids, family members, and guests enjoying the pool (after all, summer is pool party season), this is a must-have to ensure that everyone can enjoy the water safely and without risk. Highly recommended. ## Frequently Bought Together - Waterguru - Sense S2 Smart Pool Monitor - Chlorine & pH Meter - CYA & Alkalinity Tester Pool Water Tester - Spa & Hot Tub Monitor - Includes WaterGuru Sense S2 C5 Cassette, Float Ring & More - WaterGuru - Sense Skimmer Adapter - Smart Pool Monitor - Chlorine & pH Meter - Pool Water Tester - Monitor Pool Chemicals (10” Square Skimmer Adapter) - WaterGuru Sense S1 Smart Cassette - 3 Pack - Compatible with The WaterGuru Sense S1 Smart Pool Monitor only - Chlorine & pH Pool Water Testing Smart Device --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/679686773-waterguru-sense-s2-smart-pool-monitor-digital-pool-and-spa](https://www.desertcart.tn/products/679686773-waterguru-sense-s2-smart-pool-monitor-digital-pool-and-spa) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-09*
